HATCH COVER.

Original application filed October 3, 1922, Serial No. 592,060. Dividedand this application filed June 1,

provements in Hatch Covers, of which the.

following is a specification.

My invention relates to new and useful improvements in hatch covers thatare es-- pecially adapted for freight cars of the refrigerator type, andthe present application is a division of my former application, entitledHatch covers and means for looking the same, patented November 13, 1923,No. 1,473,655.

The present divisional application relates especially to the hatch coverand the way it is constructed, and has for an object to provide a coverwhich will be relatively strong in construction, relatively light inweight, and relatively cheap ,to manufacture.

Another one of the objects of the invention is to provide a hatch coverwherein the 3 wood portion of the cover will seaton the metal framesurrounding the hatch thereby providing a tighter fit than were thecontacts metal to metal, and also thus providing a better insulatedarrangement. 7

Still another ob'ect ofthe invention is to provide a hatch coverconsisting primarily of two layers of wood and a frame made from acommon form of angle iron which is easily procurable in the open market,which frame is designed to encircle the frame around the hatch and atthe same time extend inwardly a slight distance between the two layersof wood to thereby greatly strengthen the hatch cover as a whole and atthe same time allow the wood of the hatch cover to contact with themetal frame surrounding the hatch, thus forming a tight seat andallowing for any irregularities which may be present in the metal rimaround the hatch.

With these and other objects in view, the invention consists in certainnew and useful improvements and combinations of parts as will behereinafter more fully described and pointed out in the claims.

Referring now to the drawing showing Serial No. 642,819. V

a preferred embodiment of my invention, ig. 1 is a sectional view ofvahatch and the hatch cover in its closed position, and

Fig. 2 is a perspective of the frame which forms a part of the hatchcover.

At the outset, it might bestated that Fig.

- l is similar to Fig. 1 of the parent application, with theexceptionthat parts of the same have been removedf V In Fig. 1 there isshown a hatch 2 having the walls 3 extending above a car roof 4 whiletightly fitting over this wall is the. hatch frame 5 which formsthefsubject-matter of another. divisional application filed June 1,1923, Serial No. 642,818. The hatch cover 6 comprises the metal frame 7,and

an upper and lower layer. of wood 8 and 9 these layers being preferablytongue and groove formation and extending inopposite directions as maybe clearly seen from the a The frame 7 .is of angle iron constructionhaving the one leg 10 extending inwardly and its other leg 11 extendingdownwardly, the leg 10 fitting betweenv the two layers of wood 8 and9asclearly'shown in" Fig. 1;

drawing. I

a small seat being cutout in theupper surface of the under layer of wood9 so that the leg 10 may seatproperly. As is shown in Fig. 2, asufficient length of angle iron may be employed, and at the cornerswhere the bends will occur,a small V-shaped portion in the leg 10 may beremoved, so that the same may be compressed and bent rectangularly.Holes '12 are provided in the upper leg 10 at the rear of the frame sothat the hinges 13 may be bolted through the separate layers of wood 8and 9 and through the leg 10 of the frame, and in a like manner, holesare provided at the front of the frame so thatthe bracket 13 maylikewise be secured to the hatch cover, the bolt passing through theframe and separate layers of wood, thereby tying the'several parts inposition and strengthening the hatch cover. 7

Although not shown, it will be understood that if necessary, other boltsmay be used to fasten the wood to the frame. In Fig. 1, the distancebetween the frame 5 and the leg 11 of the frame 7 is slightlyexaggerated for the sake of clearness, but it will be understood thatthis distance is just enough to allowthe hatch cover to be freely raisedand lowered into position.

From the foregoing, it will be seen that a hatch cover of this type isgreatly superior to a hatch of allmetal-as it will not radiate the heator cold, as will the former,

while furthermore, the hatch cover may be tightly drawn on its seat andwill present a wood'surface to the frame5,thus allow ing for anyirregularities in the metalseat 5, and forming a much tighter joint, andalso a better insulated one.

It is also superior to an all woodenhatch on account of the rigidityobtained by the metal frame.

Again, the cover 'is one which may be easily assembled, relatively cheapto manufacture,*-and'rig'id in construction.

Many slightchanges/ might be made without in any way departingfrom thespiritand scope-of the invention;

Having pthus described" 'n'ry invention, what I claim as new and'desireto secure by Letters Patent is 1. A hatch cover comprising a body madeof a plurality of layers of'wood, a metal rim, having one leg thereofextending between two layers of'woodand the other leg extendingdownwardly below the plane of the undermost layer of;wood, the latterleg of the rim adapted to enclose the walls of a hatch when the cover isin its closed position and the rlm formi'nga frameto which both layersof wood are secured;-

2. A hatch cover' comprising a- 'metal' frame, the said frame'having" aninwardly extending flange, a layer ofheatinsulating material securedon-the flange of the frame and a second layer=of"heat insulatingmaterial secured to the under surface of saidflange of the frame, aportion of 'said frame extending below the plane of the bottom surfaceof said" lowerheat insulating 'material.

3. In combination with'a hatch-having a metal rim around its upper edge,a hatchcover comprising a metal frame, said frame having upright andhorizontal extending portions, a layer of heat insulating materialsecured to the horizontal portion of the frame and on its upper surface,and a further layer of heat insulating material se-v cured to the undersurface of the horizontal portion of the frame, the upright portion ofthe frame extending below the second layer of heat insulating materialand adapted to encircle the walls of the hatch when the cover is in aclosed position and the rim around the hatch contacting with a heatinsulating portion of the hatch cover.

4. In combination with a hatch having a metal rim around its edge, ahatch cover comprising a metal-frame formed ofangle iron,-a layer ofheatinsulating material securedto 'one leg of the frame and on the uppersurface of said leg, and a second layer ofheat insulating materialsecured tothe same leg and to the under surface thereof, one leg of theframe extending downwardly below the lower layer of the heat insulatingmaterial and adapted to encircle the metal frame on the hatch, and themetal frame of the hatch adapted to contact with a heat insulatingportion of the hatch cover when the latter is in its closed position,the one leg of the metal frame being directly abovethe metal frame ofthe hatch.
